ExtensionClass and Acquisition would fit the bill, except they aren't ported to Python3 (Acquisition needs the headers from ExtensionClass).

And there were no plans to port them either, really. :-) Only Zope 2 uses them afaik? Or?

I don't know of plans to port them, or even how hard the port would be. The "headers needed" problem is a tricky one, and they do exercise it.

Features are never backported to the stable versions. virtualenv still exists as a standalone project which is compatible with 2.7 though. Regards

It would be possible to backport the Python API and command-line UI of pyvenv (which are different from virtualenv) as a PyPI package compatible with Python 2.7. Because it wouldn't have the interpreter change, it would have to still create environments that look like virtualenv environments (i.e. they'd have to have chunks of the stdlib symlinked in and a custom site.py). I suppose this could be useful if wanting to script creation of venvs across Python 2 and Python 3, but the utility seems limited enough that I have no plans to do this.

Thank you call. Sad, but I see. I guess I could produce an extension as add-on that mutates python2.7's behavior ;-) kidding-ly y'rs - chris -- Christian Tismer :^)mailto:tismer@stackless.com tismerysoft GmbH : Have a break!
